All view and controller servlets and JSP documents require some form of support from business entities; data that should be presented in the view tends to be a controlled and limited version of the corporate business database. In the case of a financial institution such as a bank, a normal view could be the account balance of a logged-in customer. Very few systems generate such business data solely in the Web application; the majority of Web applications present data read from enterprise information systems (EIS) and laundered in a business logic tier. Most industrial-grade Web applications are designed according to the J2EE paradigm; they therefore require support from both enterprise JavaBeans (EJB)—which contain the business logic—and from large databases that constitute the EIS tier.
